The Cottagers find themselves bottom of the table with just five points from 12 games and a negative goal difference of 20. The abysmal form after gaining promotion has now led to the exit of Slavisa Jokanovic.
The club has moved swiftly to rope in a replacement in Claudio Ranieri. The Italian is famous for leading Leicester City to a fairytale Premier League triumph in 2016. He left the Foxes after a below-par start to the subsequent campaign and was in charge of Ligue 1 outfit Nantes last season.
The 67-year-old has been given a multi-year contract at Fulham.
